Curves in AutoREALM are Bezier curves, and consist of four points: two endpoints and two control points. The endpoints define where the curve starts and stops. The control points alter the shape of the curve: the further away the control point, the more severe the curvature.

Curves

A curve is a single curved section, and has a color, a line style, and line endpoint styles, and belongs to an overlay. To draw a curve, select the curve tool . Then click once for the beginning point, the ending point, the first control point, and the second control point. The cursor changes as you place points to give you a hint as to the next point required. You can use the Backspace key to remove the last point you placed.

Polycurves

Polycurves are curves with multiple sections. The starting point of each new curve section is the end point of the last curve section. Start a polycurve by choosing the polycurve tool . Then create each section as you would a curve, except you do not need to specify a starting point for additional sections. To end a polycurve, right-click and choose Create Open Figure or Create Closed Figure.

Like polylines, polycurves may be filled. A polycurve must be closed to be filled. That is, the starting and ending point must coincide. Use the second and third buttons on the color toolbar to specify fill color and fill pattern.
